Winnipeg and the Great War

More unknowns from my grandparents' photo collection. These fellows are:
  • Colleagues Grandpa met during the war who wanted him to have their portrait?
  • Close war buddies that were so unforgettable there was no need to pencil in their names on the photo or the photo holder?
  • A couple of McDonough County, Illinois, lads who wanted to get in the war so badly that they went to Canada and joined up?

It's not for me to say. Well, I can say, but I don't know. But I'll put these soldiers in orbit in cyberspace and see if someone might someday salute.
